Frankly, I have a hard time seeing regulations on the LEGAL trade of arms having a substantial impact on the trade of ILLEGAL arms. The countries with the greatest quantity of problems due to illegal arms are often going to be the countries least in a position to even implement controls on import/export of arms (think Ghana, Sierra Leone, Somalia, etc.).

Add to that the fact that a capable individual can practically build an AK out of a shovel with a couple rocks, a campfire, and some used motor oil...

Is import/export in violence-stricken countries so much an issue these days anyway? Much of what is there is "left overs" from previous wars/invasions/etc. So much so that automatic arms are freely available in quantity at "rock bottom" prices. Hell, pirates put them in plastic bags and "long line" them to appear to be fishing when approaching ships -- and are quite willing to cut the lines if they get "caught".

To an extent I can appreciate the sentiment behind the ATT idea, but it's also akin to getting a yearly Flu shot after you're already sick and have infected your whole family with the flu.
